APPARATUS FOR BURNING PETROLEUM.

SPECIFICATION forming part of'Letters Patent No. 261,791, dated July 25, 1882.

Application led December 30, 1881. (No model.)

To all 'whom it may concern:

Be it known that I, KONRAD TROBACH, of Berlin, in the Kingdom of Prussia, Germany, have invented certain new and useful Improvements in Apparatus for Burning Petroleum, of which the following is a specification.

This invention relates to improvements in wickless burners for burning petroleum and the objects of the invention are to provide a burner of novel construction which will subdivide the flarnerisin g from the burner-orifices into a series of 11a-mes; to provide means for introducing into the series of flames a continuous flow of air for oxidizing the llame, and to regulate and control the supply of such air, and consequently modif'y the intensity of the heat. These objects Iaccomplish by the construction of burner illustratedin the accompanying drawings, in whichigure l represents a vertical central section of a wickless petroleum-burner constructed in accordance with my invention, and Fig. 2 a transverse sectional view on the line x m of Fig. 1. p

Referring to the drawings, the letter A indicates a main oil-supply pipe, supporting the burner and adapted to connect with a reservoir containing the petroleum or other fluid to be burned. This pipe at itsalpper end is providedI with an annular chamber, A', `from which project a series of vertical tubes, A2, arranged in an annular row, as shown in Fig. 2, and which connect at their upper end. with an annular chamber, A3, from the centerlower part of which depends a pipe, A, having at its lower end a lateral mouth-piece or chamber, A5, the upper wall of which is provided with burner-orifices a, located outside the depending pipe.

A sleeve, B2, loosely surrounds the annular row of tubes A2, and is adapted to be moved vertically by the provision of any suitable mechanical contrivance; such, for instance, as a rack andY pinion; but I contemplate making the sleeve hug the pipes snugly, so that the frictional contact will be suicient to retain the sleeve in its adjusted position.

The upper edge Vof the sleeve is provided with an outwardly-flaring flange, B3, on which rests or is attached the contracted end of a `series of tubes A2, the

perforated truncated cone, B', to the upper wide end of which is secured a funnel, B, which projects downward and surrounds the major portion of the burner. It will be obvious that by the vertical movement of the sleeve the funnel will be correspondingly adjusted.

In operation the oil ascends through the pipe A under pressure and enters the lower chamber, A', from which it rises in the series of tubes A2 into the upper chamber, A3, and it then flows down the central depending tube, A4,into the mouth-piece or lateral chamberA5, where it is heated and burned at the burnerorices a. The llame rising from the burnerorices a is divided above the upper edge of the sleeve B2 by passing or issuing laterally through the spaces intervening between the series of vertical tubes A2. The heat of the flame causes an ascending draft of atmospheric air through the funnel,which air passes through the perforated truncated cone or plate B and mixes with the series of amles, thereby insuring perfect combustion and oxidation of the same. The draft of air is controlled by the vertical adjustment of the funnel, and consequently the intensity of the flame can be pegulated. The oxidized llame caused by the air-draft constitutes a petroleum steamblast, the heating power or intensity of which can be controlled by regulating the supply of atmospheric air through the medium of the adjustable funnel.

Having thus described my invention, what I claim is- 1. An oil-burner combining in its structure a main oil-supply pipe, A, a series of tubes, A2, end chambers, A and A3, depending pipe A4, provided at its lower portion with burneroritces, and an adjustable funnel, B, substantially as described.

2. The combination of the main pipe A, the end chambers, A and A3, the depending pipe A4, having burnerorifices a at its lower portion, the movable sleeve B2, surrounding the series of tubes,and the funnel B, movable with the sleeve, sub Y stantially as described.

3. The combination of the main pipe A, the series ot' vertical tubes A2,

the end chambers, roo

movable with y In testimony whereof I have signed my name to this speeication in the presence of two sub- :o seribing witnesses.
